Others didn't believe it, so they rolled up their sleeves and touched it themselves.

It's all hot in a jar of water, but I haven't found any way out.

"I don't have an instruction manual, I really can't understand this. ”

"Is it also an agency? It's not realistic to do this as an agency. ”

"This is the model, and then we will build the tunnel according to it, and it is even more impossible for the tunnel to be mechanical. ”

Discussions came and went, and no one dared to try to dismantle it.

After all, it's all soaked in water, and if it is not dismantled, the cracks are exposed, and it is too late to remedy it.

They don't need to be others, they won't let go of themselves.

"Alright. Chief Engineer Su twisted his eyebrows, circled the water tank twice, and looked at the sky outside, it was already bright: "Let's go back to sleep, postpone it today, and gather again at half past nine." ”

According to the past habits, Master Lu and the others also came here at ten o'clock.

In fact, everyone was quite sleepy, and it was impossible for them to wake up Lu Zi'an and ask them, they had not found a way, and they were a little tired.

Chief Engineer Lin also agreed with Chief Engineer Su's statement and waved his hand: "Let's go back, I can't see a result anyway, wait for Master Lu and them to come." ”

Although they were a little unwilling, everyone still left as they said.

A few immortal hearts who like to drill the horns of the bull circled around a few more times and walked away.

Chief Engineer Lin was still the last to go, checked the inside, locked the door, and he yawned and went back to the dormitory.

The crowd in front of them discussed in a low voice, and the voices came from afar, as if there were nothing.

“…… It feels like there must be a mechanism for this. ”

"I don't know...... What the hell is this...... What's going on, I touched it all and I couldn't find a seam......"

"Didn't you cut a whole piece of wood?"

"That won't ...... either"

Guess and guess, even if they are lying in bed, few people can sleep.

Everyone pricked up their ears and listened to the movements in the rooms of Lu Zi'an and their master and apprentice.

Silently.

At nine o'clock, many people got up to wash, and it was still quiet next door.

When they went to the cafeteria, they didn't see any of Lu Zi'an's master and apprentice.

At half past nine, they arrived at the conference room, and the room was full of people's eyes.

"What about people!?"

Chief Engineer Lin coughed and came out to preside over the overall situation: "Maybe, Master Lu is a little tired, let him rest, in this way, let's discuss it today first, about this ......"

He quickly found a new topic to analyze and discuss in detail, but the others were clearly lacking interest.

Even the most active engineers on weekdays are a little absent-minded.

Lu Zi'an had actually woken up a long time ago, and his biological clock was too strong.

But he thought that he had promised to give them a half-day off today, and if he got up, Ying Xuan and the others would definitely be embarrassed to continue sleeping.

Thinking so, he simply chatted with Man Man in the bed for a while, and when Man Man was in class, he yawned again and fell asleep.

When he woke up, it was already eleven o'clock, and he washed up slowly, wondering whether to eat some noodles or eat.

This is breakfast and lunch, right......

I was still thinking about powder or rice in my head, and as soon as I opened the door, a few people standing outside turned around: "Master Lu, are you awake!?"

Lu Zi'an was a little stunned, and nodded: "What are you doing here?" ”

He was a little frightened, as if he was in a vegetative state and had finally woken up, and looked at the excitement on their faces.

"Master Lu, will you go to the conference room or the office first?"

"You must have eaten first! What do you want to eat? Why don't you go directly to the conference room, and I'll bring you food?"

The guards on the side looked at him vigilantly: "I'll just go and get dinner...... "What about robbing him of his job?"

The others were embarrassed to catch up, but their eyes were eager.

Lu Zi'an listened for a while and heard something interesting: They seemed to want him to go to the conference room?

What's in the room? He raised an eyebrow, and suddenly understood.

"Okay, then bring me some food, I'll go straight over. With a faint smile on the corner of his lips, Lu Zi'an followed them down the steps.

Everyone surrounded him and just walked a few steps, and Ying Xuan behind him also opened the door and walked out: "Master?"

"Oops, Ying Xuan!"

So Ying Xuan and the others were quickly taken to the conference room, and the engineers next door who couldn't hold back for a long time were even more moved.

Chief Engineer Lin, who said that he would continue after a ten-minute break, went out to smoke a cigarette, and when he went back, he looked at the empty conference room and was a little confused: Who am I, where am I, and what am I going to do?

Like the stars and the moon, Lu Zi'an and his entourage were pushed to the forefront.

"There's a switch here. Ying Xuan was very strange: "Just press the switch directly." ”

"The switch is to turn on the light, and we want to know if there is any other use for this tunnel. ”

Lu Zi'an nodded very naturally: "Of course there is a way, it's actually quite simple, that's it." ”

At both ends of the artificial island, there is a section of bridge, gently resist the two ends of the bridge, and push hard.

The bridge can be switched left and right, which is also to make people more intuitive to see the exquisite design of the whole bridge when switching left and right driving.

After the switch, the center of gravity of the entire artificial island shifted, and the two ends slowly sank, and the tunnel slowly rose.

The moment the water came out of the tunnel, everyone held their breath.

It's not a particularly subtle design, but the way it switches is really amazing.

The bridge of the model is not long, so this kind of switching seems to be urgent, but if it is actually applied to the bridge, in fact, such a switch is very gentle.

"When you're actually driving, you don't actually feel the switching, it's a very natural and comfortable left-right switching. Lu Zi'an explained while demonstrating: "This is also in line with the topics that everyone discussed and studied before......

With his words, the tunnel rose to a certain height and stopped.

Still touching the joints with your fingers, a small section of the tunnel can be removed with a gentle tap.

But the difference is that this time the model is very precise, and it even uses a lot of technology that they have studied and obtained results in the past.

This time, Lu Zi'an was still ahead of them.

While they were still complacent about the idea and trying to find the relevant content to prove that it was indeed possible, Lu Zi'an had turned it into a reality.

This tunnel immersed tube passed silently in the hands of everyone, and everyone couldn't put it down.

When it was passed to Chief Engineer Lin, he looked at it for a long time before handing it to Chief Engineer Su and looking up at Lu Zi'an: "Master Lu, now that the two artificial islands in the east and west have been built, will this tunnel be built first, or will it be built later?"

"At the same time. Lu Zi'an's answer was very simple and rude: "I am going to divide the labor into two groups, one group blows sand to build islands, and one group carries out the initial construction of tunnel immersed pipes." ”

It can't be too early or too late, the key is to control the time.

"I'll keep an eye on the tunnel, the model of the artificial island is a ...... we made together" Lu Zi'an's tone changed, and he looked at Ying Xuan calmly: "The construction of the artificial island will be followed up by Ying Xuan." ”

The conference room fell silent.

Chief Engineer Lin and Chief Engineer Su actually have no opinions, they are chief engineers, and all aspects will be controlled in place.

Even if it is the project that Lu Zi'an is responsible for, they will also follow up, so whether there is a division of labor or not makes no difference to them.

The other engineers didn't have much of an idea except for some surprises, after all, this model was in front of them, and they couldn't figure out where the switch was, even if Lu Zi'an said that he would hand over the project to them, no one dared to take it.

Therefore, on the contrary, Ying Xuan himself was a little confused.

He was stunned for a few seconds, and in the face of everyone's eager, suspicious, or admiring eyes, he opened his mouth, and finally met Lu Zi'an's approving and trusting eyes, and nodded stiffly.

In the conference room, there was applause.

Ying Xuan was a little panicked, shook his hand, and felt that his palms were full of sweat.

"Well, my meal is here, the next steps, you can talk about it. Lu Zi'an looked at him with a smile.

"Yes, yes, Master Lu, you eat first, don't go hungry. ”

Everyone rushed up and began to ask questions around Ying Xuan.

Ying Xuan was a little nervous at the beginning, but when he got to the point, he was in good spirits.

The two artificial islands are easy to disassemble and assemble in the palm of his hand, and this model is particularly exquisite, from large houses to small flowers and plants, all of which can be dismantled and moved.

If this is all there is to it, it will be too much of a disappointment to Lu Zi'an's hard work.

The engineers watched Ying Xuan disassemble the tunnel as if by magic, and then assemble it in the water, and their eyes were straight.

"Aren't you afraid of getting into the water?"

Ying Xuan's reply was quite an understatement: "The real thing is also like this, otherwise such a heavy immersed tube, no matter how big the crane is, it can't lift it." ”

Thinking of the giant immersed tube outside, everyone nodded thoughtfully.

It seems that the immersed tube will be like their model, first sealing the two ends, docking and then removing the seal.

However, this has very strict requirements for the accuracy of docking, otherwise once there is an error, water ingress is no joke.

"According to our calculations...... Chief Engineer Lin has been able to recite these data backwards: "The water flow at the head of the island is extremely complex, and it is possible to form whirlpools, which will bring sediment siltation, so that there is a certain deviation in the height of the seabed foundation, and the deviation may reach 5 to 10 centimeters." ”

This is the "first kiss of the deep sea"...... Are you sure?

Ying Xuan's steady tone: "I am in charge of the construction of the artificial island, and I will try my best to cooperate with the construction of the artificial island to facilitate docking." ”

However, what they are worried about is not only the problem of the docking of the buried joint of the artificial island and the first section of the immersed pipe, but also the placement of the final joint.

Different from other immersed tubes, the final joint is the control hub of the immersed tunnel breakthrough of the Hong Kong-Zhuhai-Macao Bridge, and it is also the last link of the whole line.

It is not transported from the water, but is lifted into the seabed by a crane ship, and after entering the water, it will be affected by ocean currents, buoyancy, etc., and the attitude will change.

In order to ensure the smooth water stop after the hoisting is completed, the height difference must be controlled within 15mm.

And, it has to be right the first time.

In response to their questions, Ying Xuan answered more calmly: "I'm sorry, I'm really not sure about the content of these projects, so the project related to the tunnel immersed tube will be controlled by my master himself." ”

It doesn't matter if I'm weak, who let me have a backer!

There is a Master for everything!

Engineers: "......"

They subconsciously glanced at Chief Engineer Su and Chief Engineer Lin, and their eyes were obvious: Look at people!

Chief Engineer Su and Chief Engineer Lin: MMP.
